So, it's a semi-long story (see my post in the welcoming thread), but I've got a single common goldfish in a ~1 gallon bowl. And, unfortunately, that's where he's got to stay 'til we get him a nicer place.
I'm doing about a 35% PWC daily. The fish seems healthy and happy. He eats fine and swims around a lot (despite the lack of room ), but the only thing I'm a bit worried about is oxygen supply. Nothing is disturbing the water surface to generate a lot of air exchange.
Would an airstone be a good solution for this problem? How do they work?
Oh, and another side question... despite the fact that the mouth is turned up (which is supposed to indicate a surface feeder, I think), I've heard goldfish dig around in the substrate a lot for food. So would floating or sinking food be better for him?
